Sixth iteration of Apple iPhone, announced on September 12, 2012. Repair of this device is similar to the previous models, requiring screwdrivers and prying tools. Available as GSM or CDMA / 16, 32, or 64 GB / Black or White.

Screen clicks randomly by itself

My iPhone 5 is acting crazy. It is clicking by itself randomly and the screen is randomly unresponsive so suddenly it responds. I changed the touch screen twice, reinstalled IOS from scratch. Nothing of this helps. It is still acting crazy.

Here are some pictures of the digitizer connector. Were you wondering if there were any uncovered contacts?

Some pictures of the connector here:

Here is the connector after I cleaned it with isopropanol and a soft toothbrush:

Gently scrub the connectors on the board (in the picture) using a soft brush and a little bit of 90%+ isopropyl alcohol. Any change? (Keep the alcohol away from the screen, it will damage it)

A few things I noticed on your phone: connectors are dirty. There is something on them (at least one of them) that would require cleaning as per the above.

And one of the screw brackets is gone. And may be the black *foil* covering the area between the cable connectors is disturbed, as if it was previously removed then put back. What is the history of this phone? Did you get it new or used? Did it suffer from any incident such as drops, liquid damage, etc.? How/when/why did it start acting crazy? Following any particular incident?

Here is the history. Someone gave me this iphone probably because of the issue. He had sent it to repair but they have done a bad job, e.g. you see the missing screw thread. I was told it was not dropped or had liquid damage but I could be wrong on both events. The liquid indicator to the bottom right of the battery is white.

Can you remove the black "foil" VERY VERY carefully? The one covering the area around the connectors on the board. And post a picture if you see any missing component there between and around the connectors?

Just to say, that in my experience, crazy touch is usually due to a bad screen/cable or to a bad connector on the board. However, I've encountered issues that occur from damaged parts that at first do not seem related. Which is why I always start by examining all visible parts of the logic board, looking for anything damaged even if *apparently* not related.

I removed the black foil and took a picure. I am not able to see any damage or missing parts. Do you see anything here? Hope the pic is good enough. Thanks for hanging in with me on this. I really appreciate it :-)

@Rany I have tested this exact digitizer and it works perfectly in another iPhone 5. Also the LCD is not consistent in colors when attached to the iPhone. It is lighter in the middle, like a brighter block in the middle of the screen.

We don't see any visible damage on your digitizer connector or surrounding area in the picture. But still, I would expect this to be related to the connector. I would think it would be worth it to try a connector replacement. I would offer that as a solution for you in this case---If you want to do a mail in repair I would quote this as a "solution' i.e solve the ghosting problem with a new connector or no fee.
